One troy ounce sterling silver spacer bead strands. Spacer beads can be used as single spacers between large beads or in multi-bead stacks. Strand lengths will vary according to bead size. Each strand weighs 31.1 grams--a true troy ounce. These are individually hand-made, so the number of beads will vary per troy ounce. This package will contain approximately 160-180 beads. Sizes, shapes and colors may vary with handcrafted items.
